I am a little late to this thread, great suggestions so far, I further suggest a glow disc, flash light, firewood, more beer than you'd expect, and the following:
A big tarp and some rope and bungie cords. You can easily make a dry shelter. Tie rope between two big trees as high as you can, stand on top of vehicle if necessary, drape tarp over rope, tighten rope with bungies thru eyelets attached to whatever you can (additional trees, vehicle, tent poles, etc). The bigger the tarp the bigger your makeshift dry area. Similar to an 'A' frame type set up. This system also works good on a smaller scale attached to the back of an SUV for day tourneys.
Good luck to all! Stay dry my friends!
Hope this is helpful too all PNW golfers & campers!
I remember on year when I was little camping at the Coast during spring break and it rained every day. Tarps are NW car camping essential (as well as a near by Laundromat). The more the better we started with 2 and by the end of the trip we had about 6 or 7. The smallest size tarp I would recommend is 8’ by 8’ or buy yourself one of the “ez-up” type shelters they are great and worth every penny.
